Investigation the Elemental Composition of Some ‘‘Kohl’’ Samples

Abstract

This study was aimed to investigate the most major elements, in kohl, as a traditional cosmetic material used by Sudanese. Eight Kohl samples from different sources were purchased from Khartoum state markets, and subjected to elaborate analysis by inductively coupled plasma Optical Emission Spectrometry, to detect the presence of a wide range of minerals. The analysis showed the occurrence of twenty seven elements. The lowest concentrations were shown by Boron (<0.001875 ppm) and Lithium (<0.000387ppm). Very higher concentrations were shown by Lead, Iron, Zinc and Manganese. Calcium, Sodium, Magnesium and Potassium contents, were relatively high. Molybdenum, Phosphors and Aluminium showed various concentrations in the eight samples.
